PlumeIMPACT - Lithospheric Delamination by Thermochemical Plume Impact

Model setup and boundary conditions.

The 3D box size is 57° x 57° x 1900 km. The lithospheric thickness varies from 100 to 150-200 km. The initial plume-head geometry varies from 300 to 500 km diameter and is filled with tracers (1 million). Also an initial 50 km thick tracer layer covers the bottom of the box. The top boundary condition is either free-slip or kinematic (2 cm/yr). All lateral boundaries are reflecting. The bottom face has a zero velocity imposed. Below you can see the modelling results after modifying different parameters.
